Subduction Zone Volcano Formation Diagram | Geology Education #3584283 (License: Personal Use)

The image depicts a cross-section of a convergent plate boundary where an oceanic plate subducts beneath a continental or another oceanic plate; friction and heat cause partial melting in the mantle wedge, forming magma that rises to erupt as a volcano. Arrows indicate plate motion, the red dot marks the magma source, and layers represent crust, mantle, and overlying water body. The surface shows a stratovolcano emitting gas plume.
